Actually, cache on xfs mounted with atime doesn't seem to be a performance
killer oddly enough... Our frontends had no problems surviving 1k
requests/s during the latest mozilla-update-barrage.
1k requests/second is not really that much... 10k requests/second is more
what I'm used to. XFS sucks for us as a cache storage. It tends to crock
under some traffic patterns (reads vs writes). ext3 is actually more
reliable for us. Reiserfs is interesting, but tends to go haywire from time
to time.
I think the key difference here is our average file size... We don't
need that many requests/s to bottom out gige normally.
We clean our cache often because we have a really quick way to find the size
and remove the oldest expired objects first. Every cache store gets recorded
in SQLite with info about the object (size, mtime, expire time, url, key,
etc.). Makes it trivial tow write cron jobs to do cache management.
Yup.
